I downloaded the source (version 1.10.1) and attempted to build it in
mingw on a Windows 7 computer. Here is the configuration I used:

$ python configure.py --disable-shared

Here is where the error occurred:

$ make

src\utils\dyn_load\dyn_load.cpp: In member function 'void*
Botan::Dynamically_Loaded_Library::resolve_symbol(const std::string&)':
src\utils\dyn_load\dyn_load.cpp:68:56: error: invalid conversion from 'int
(*)()' to 'void*'
make: *** [build\lib\utils_dyn_load.obj] Error 1

Here is the gcc version:

Using built-in specs.
Target: mingw32
Configured with: ../gcc-4.5.2/configure
--disable-sjlj-exceptions --with-dwarf2 --enable-shared --enable-libgomp
--disable-win32-registry --enable-libstdcxx-debug
--enable-version-specific-runtime-libs --disable-werror --build=mingw32
Thread model: win32
gcc version 4.5.2 (GCC)

I tried passing --with-tr1=none to the config. Same error. Any suggestions?
